One thing to note when using any microbial slurry bugs is the presences of dairy chemicals, footbath solutions, wormers and antibiotics. They all kill microbes so the effects of a slurry treatment can vary massively depending on what's going in the slurry. There is at least one slurry conditioner that I know of that neutralises these and allows the microbes to work better, otherwise the microbes are all much of a muchness, bit like silage additives. Retention of N, less crust, less smell and easier to spread (umbilical especially) are all expected results of a successful treatment.
Growers and agronomists now face the dilemma of an early application to remove competition from emerged wild oats, or holding off to allow more weeds to germinate.
Syngenta grassweeds technical manager, Georgina Wood, urges Axial Pro treatment as soon as conditions allow, once weeds are actively growing.
“That offers the chance to control wild oats more cost effectively at lower rates, whilst there is still the flexibility to tailor application rates up to 0.82 l/ha for larger or over wintered weeds and difficult situations.
“The variability of crops and situations this season means decisions for appropriate Axial Pro rates and application techniques will need to be made on a field-by-field basis,” she advised.
